The
Explanation of Solution
Given information :
Sara has 10 pound of dried fruit selling for
Pounds of mixed nuts selling for
Let
Calculation :
1 pound of mixed nuts
Therefore,
And
1 pound of trial mix
Therefore,
Pound | Price per Pound | Total Price | |
Dried Fruit | 10 | ||
Mixed Nuts | |||
Trial Mix |
Hence, the
b.

b.

Answer to Problem 9CYU
The rational equation is
Explanation of Solution
Given information :
Sara has 10 pound of dried fruit selling for
Pounds of mixed nuts selling for
Calculation :
Pound | Price per Pound | Total Price | |
Dried Fruit | 10 | ||
Mixed Nuts | |||
Trial Mix |
The total price for dried fruit is
The total price for mixed nuts is
The total price for trial mix is
Therefore, the rational equation is
Hence, the rational equation is
c.
To solve : the equation to determine how many pounds of mixed nuts are needed
c.
